The genome sequence of the hoverfly, Brachypalpoides lentus Meigen, 1822 (Diptera: Syrphidae)

We present a genome assembly from an individual male Brachypalpoides lentus (hoverfly; Arthropoda; Insecta; Diptera; Syrphidae). The assembly contains two haplotypes with total lengths of 1 315.37 megabases and 1 154.75 megabases. Most of haplotype 1 (95.66%) is scaffolded into 6 chromosomal pseudomolecules, including the X and Y sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.88 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
